The Smeltery Drain is a component of the multi-block structure known as the Smeltery. The Smeltery Drain can function as both an input or an output for the Smeltery, and thus a working Smeltery requires at least one drain. Only space limits the number of Smeltery Drains that can be added to a Smeltery. With a Seared Faucet attached, the Smeltery Drain will allow the Smeltery to pour molten metal into a Casting Table, Casting Basin, Casting Channel or Seared Tank. Smeltery Drains are also able to interact with fluid pipes from other mods, including Buildcraft's Fluid Pipes and Thermal Expansion's Fluiducts.
